Brief Summary

Here's an instance where the term "entry-level" is a misnomer -- we only call her that because of her size and price. This boat lacks for very little and has a top speed of 50.6 mph with a single engine. She also has amenities such as Cruise Assist and No Wake Mode.

All fuel consumption numbers are the total for all engines in the boat. Speeds are measured with Stalker ProSports radar gun or GPS. Fuel consumption (gallons per hour) measured with Floscan digital fuel-flow meter or by on-board factory-installed diagnostic instruments. Range is based on 90% of published fuel capacity. Sound levels determined using Radio Shack digital decibel meter on A scale. 68 dBA is the level of normal conversation. Time to plane is measured from start of acceleration to formation of rooster tail behind boat.

Captain's Report

Captain's Report by Capt. John--

The Yamaha SX192 is a 19’2’’ sportboat with a single supercharged engine powering a jet-drive unit.

Start with the Facts

The SX192 weighs in with a dry weight of 2,150 lbs. which is important to note since she is one of the lightest boats in class, and lighter than some 18' models. Leaning on its experience in PWC design and its larger twin engine jet boat designs, the 192’s hull is a marriage of all that the team at Yamaha has learned over the years. Not only does Yamaha manufacture and assemble the entire hull and deck components, they also design and build their own engines. In our opinion, this is a huge advantage from a service, reliability, and warranty point of view. It sets Yamaha apart from their competitors. The power comes from the 1.8L, four-cylinder, four-stroke, 16 valve supercharged purpose-build Yamaha Marine engine. The 16 valves provide greater efficiency in how the engine breaths while the supercharger boosts horse power by forcing more air into the engine.

The 1812CC supercharged engine is compact and sits neatly under the center aft seat. It is easily accessed.

At the transom the deadrise is 18 degrees and because this is a jet drive power system, the draft is only 14”. This shallow draft is due to the fact that there is no lower unit or an outboard prop down below the bottom of the hull. This provides for excellent skinny water access. Her beam is a 8' (2.43 m) and she carries 30 gallons (114 L) of fuel. Even though this is a high performance engine, it has been optimized to run on regular 87 octane unleaded fuel. The jet drive unit consists of a three blade stainless impeller with a 14.3-degree pitch.

Yamaha’s Total Package includes everything you see, including the trailer. There are no options to bring up the attractive price.

Interior

Starting forward, Yamaha knows how much fun it is to anchor off a beach or in a quiet cove. With this in mind, the 192 has a molded-in, self-draining anchor locker with room for line.

The anchor locker on for the SX192 is positioned under a pull up step cover at the bow. There are two cleats, one to port and starboard to secure the anchor line.The SX192 has a distinctive bow flare shape to allow for more room all the way forward.

When looking at a side view of the SX192 it is obvious that the interior width is pushed as far forward as possible, creating a distinct push out or flared look where the hull and deck meet. This was necessary to provide enough room for adults up at the bow. There is storage under the bow seating with the port side opening up into the console behind design for your large and longer items.

The sleek helm layout is a simple, uncluttered design. The throttle is well positioned and the gauges are tucked under the dash brow.

At the helm is the cruise assist which allows the throttle to be set and then increased or decreased by clicking up or down on the rocker button. There is also a three position no-wake mode, actuated via a rocker switch so idling in and out of the marinas takes just the push of a button. The “U” shape seating wraps around the aft cockpit. It features the plush, high-quality upholstery that is standard on Yamaha’s entire lineup.

The SX192 has matching seats for the helmsman and observer. They feature open backs and flip-up bolsters.Portside glovebox lockable storage with 12v outlet, MP3 jack and stereo controls.

To port in the console is storage bin which also has a 12v outlet, the MP3 jack and stereo. This is held open by a spring support. A gutter runs around the edge, to help keep things dry inside.

The above image shows an aft storage compartment just behind the helm seat which accommodates a full size cooler. The black cap to the right of the picture is the engine flush out port. Since these boats are designed for both fresh and salt water operation, Yamaha added this quick connect feature so a fresh water hose can easily be hooked up to flush out the engine cooling system without opening the engine compartment hatch.Custom cut snap in carpeting is standard for all Yamaha models. The SX192 has additional sole storage centered in the walk through. This is a good wet storage bin since the drain is connected to a hose that leads overboard and not into the bilge. Full marks to Yamaha for this feature!

The next area is one that we have been showing on Yamaha boats for years: the stern seating and swim area. Since the engine is so compact, it allows the designers to provide boaters more usable space at the stern.

The stern seating has comfortable back rests with cup holders to either side and a ski point on centerline. The cleanout port for the jet drive unit is under the seat. The swim ladder is located under the swim platform and the addition of two grab handles will make reboarding easier. The waterjet propulsion requires no exposed propeller, which has obvious advantages for a family with small or younger kids.

All Yamaha’s engines are built of corrosion-resistant alloys, suitable for fresh or salt water use. This impeller is the heart of the propulsion unit.

Performance

This nineteen-footer, from the tip of her roomy bow seating area to the output of her 1.8 liter supercharged engine, is one little fun machine. Heading off the dock, she was responsive. I never felt like I had to react to the maneuvering peculiarities of a jet drive as I’ve had to do in the past with earlier models. Sure, she’s a nineteen-footer at an attractive price, so I didn’t expect to be riding in the lap of luxury. But Yamaha’s automated production efficiency and attention to detail has provided a feel of luxury I don’t normally expect to find at the entry level in a boat that is all about water sports. Our test boat tipped the scale at 2660 pounds, including two of us on board. As we accelerated, the GPS struggled to keep up with us as we were on plane in 3.5 seconds and the needle hit 30 in 5.1 seconds. The hull seems to be a perfect match for Yamaha’s purpose-built engine, and I understand that the hull shape is the result of a bunch of tweaking to get the shape of the entry just right. It felt good to me. Our best cruising performance was observed at 5500 rpm where we saw a speed of 25.55 mph using fuel at a rate of 8.3 gph for a range of 83 statute miles, and our top speed was 50.6 MPH at 7700 rpm, wide open throttle. An improvement I look forward to seeing from Yamaha is full fly-by-wire throttle control. Right now, the throttle lever is linked to the electronic controller by aviation-type wire linkage. Since they already have the electronics in place, it makes sense to me that they should make this change one of these days. On the other hand, one improvement they have made is very effective indeed; it’s called “Thrust Directional Enhancer” and it serves to improve slow-speed handling. It sounded like a sales pitch to me, but I’m pleased to say that my skepticism was proven wrong. This is the most maneuverable jet drive boat that I have ever brought in to a dock. I’m sure a beginner could feel confident right out of the blocks. Between her ease of maintenance, standard features, and attractive price, it’s not a wonder that Yamaha seems to get more popular with boating families every year. We think this new model offers all the standard features one would expect in a larger boat, but with the twist of industry-leading engine technology. This boat comes with a painted trailer as a complete package starting at $30,999.

Test Result Highlights

Best cruise for the Yamaha SX192 (2013-) is 25.5 mph (41 kph), and the boat gets 3.07 miles per gallon (mpg) or 1.31 kilometers per liter (kpl), giving the boat a cruising range of 83 miles (133.58 kilometers).
